There’s nothing better than a manicure that looks fresh from the salon, especially one that is a fraction of the usual price — hence, our obsession with press-on nails. From classic French tips to elaborate mermaidcore and chrome designs, you can find press-on nails in almost any style you can dream of nowadays. Once you decide on a set you love, however, it can be tricky to know how to apply the nails. During application, you might notice small air bubbles start to form. These can happen for a lot of reasons, but most often they’re due to not using the correct nail size, skimping on glue, or pressing down too hard on the nail, says Ann McFerran, CEO and co-founder of Glamnetic. “Air bubbles are not only unattractive, but can make the nails fall off sooner and can trap unwanted moisture,” McFerran explains. Below, the pro shares how to apply press-on nails and avoid pesky air bubbles.
